Small transformers
Small disconnector transformers TVTR
In these devices the primary coil is separated from the secondary coil by a basic insulator. They can be used for power transmission, control,
signalling actuating or other low voltage electric circuits, e.g. to generate functional low voltage (FELV) according to the standard
HD 60364-4-41 or to perform electrical protection to a secondary consumer with simple insulation.
The transformers deliver one-phase power with eight different secondary voltage values (Usec=3-6-12-18-24-42-110-230 V).
The transformers are built in conformity to the requirements within EN 60742 and EN 61558. Their degree of protection is IP00, i. e. they are
meant to be built in as parts into another equipment. Connections are ensured by screwed connectors with IP 20 degree of protection. Rated
powers range between 50 – 630 VA, depending on construction. The secondary coil has more wiretapping exits. The rated power refers to the
highest secondary voltage value. At the other wire-tapping exits the transformer delivers proportionally lower power values (see table).

Small transformers
One-phase insulating transformers TVTRB
These products are meant for insulating separation in low-voltage power transmission, actuating, signalling, control and other circuits, to
generate shock-proof low voltage (SELV) according to the standard MSZ HD 60364-4-41. A protective separation is built in between the
primary and secondary coil. The safety insulating transformers deliver at the secondary side so-called safety low voltage below 50 V. The
insulating transformers deliver at the secondary side low voltage above 50 V.
All our transformers satisfy the requirements set within EN 60742 and EN 61558. Their degree of protection is IP00, i. e. they are meant to
be built in as parts into another equipment. Connections are ensured by screwed connectors with IP 20 degree of protection. Rated powers
range between 60 – 600 VA, depending on construction. The secondary coil has more wire-tapping exits.
The rated power refers to the highest secondary voltage value. At the other wire-tapping exits the transformer delivers proportionally lower
power values (see table).
